براغي رأس سداسية M12-1.75 × 180 مم | فولاذ فئة 10.9 زنك أصفر | ملولبة جزئيًا (20 / عبوة)

The partial threading is exactly what I needed for a jig build—the grip section holds firm while the blank end lets me stack washers without fighting the threads. Class 10.9 zinc coating looks clean and the heads are crisp, no burrs.

The hex head grabbed a socket perfectly on the first try, and the yellow zinc finish looks like it'll shrug off shop grime for a long time. These 180mm bolts were exactly the right length for the frame I'm bolting together, and the partial threading made alignment a breeze.

I needed a longer bolt for a jig I was building, and the 180mm length on these was just right. The partial threading made installation into my tapped hole much easier than a fully threaded bolt would have.
